Watching some British movies and series, I noticed that the speakers usually use the sound /a/ instead of "schwa" in the end of some words, such as "suffer", "differ", "better" and "water". Is this affirmation right? Can I say that this is one of the linguistic phenomena in the English language?
Yes, I'd say some accents in Britain would be using an 'a' sounding vowel at the end of such words. Most likely a broad cockney accent - around the London area.
This is shown in how such speakers type in their own dialect - 'bruvva' for 'brother', 'whateva' for 'whatever'.
